My beloved husband Ron Gordon, may he rest in peace, died in October. He was an avid chip collector. Among his things, I found a $1000, a $500, and two $100 casino chips from Crystal Park Casino, Crystal City, CA. One of the $100 chips appears to be older...it is different from the other $100. Did Ron buy these from anyone here?? I hate to ask, but I am at a loss here. Can anyone give me an idea of what each of these is worth? Thank you so much.
